Okay I know theyre not the best cut of meat but I wanna see one of those Mcdonalds food experiments done correctly. Not just where they sit the food on the counter and show you what it doesnt do over a period of days because:
1. You dont swallow food whole… so the food you plan to show/expose needs to be broken down a little more first
2. Your stomach is much more acidic than the air….so Im sure, if enclosed in a jar with fluid similar to the Ph of stomach acid this process would not be at a stand still
3. Your stomach growling isnt just you being hungry..it does that when your stomach muscles contract to further break down food…so add some muscular movement to that jar because food doesnt just sit stationary on a counter in your stomach during digestion…

If after all that Mcdonalds food STILL doesnt breakdown i’ll be impressed and stop eating it. Until then Im gonna enjoy these chicken nuggets :)
